please wait a little bit:

My message was a false positive.

1. The msvc in my office and at home is still not satisfied by the 
patch. I really dont know why!
There are ?arbitrary? circumstances, witch led my compiler hang up, but 
not eon every run !!.

2. Is this still to be called "/* explicit vectorization */"? Please 
give me some basic information about that. Then maybe i can look out for 
an other, smarter, solution.

3. There several places in cachefriendlyproduct.h witch possibly could 
cause the same problem (by arbitrary circumstances?).
What I'm mean is: Why does line #504 (below "process remaining coeffs 
(or all if there is no explicit vectorization)") or line #522 (below 
"process first unaligned result's coeffs") not causing the exact same 
problem????

4. Rev #917843 cause several warnings and errors (see some of them below):

Cheers
